For Analysis of the image the most commonly used technique is Edge detection is one of the most commonly used operations in image analysis. Different techniques have been discussed and compared earlier by researchers. Different edge detection techniques such as Sobel, Prewitt, Robert, Canny, Log, and OSTU have been used. Various examples are found for an application of edge detection technique on normal raster based images. But to detect an edge of object present in geographical data or in satellite images there is need to recognize best edge detection technique. Hence present research work has been focused on comparative study and implementation of various existing classic edge detection techniques and proposed Cellular Automata edge detection technique to detect an edge of an object present in satellite imagery data.
